UNITED# STATES PATENT -O1=1=1OE JOHN I1. KINKAID AND sTAN'I'ONfII, WESTON, or Los ANGELES, CALIFORNIA, AssIGNOEs OF ONE-THIRD '11o ROBERT D. PEAEsON, OELos ANGELES, CALIFORNIA GASKBUENEE Application' filed Yrune 1K9,

Thisfinve'ntionrelates to a rotary burner particularly "adapted to move through the vatmosphere theflame produced by the burning gaseous-fuel, in'such a manner as toburn l5 a maximum' amount ofy the 'atmospheric oxygen;

An objectl of the invention is tovprovide -an'exceedingly simple and dependable appliance of the character stated, one that .can be V10 manufactured at a low cost, and lthat may rotary burner member and the supply-.con- A' 20 duit whichfleadsthereto.y

Yet another object is to provide-a burner particularly well adapted to expandy by heat, rings or likecircular metal'objects in order thatthey may be shrunk'v in place upon me- 25 tallic parts .upon which they'are to 'be mounted. Y

When. the device is used for burning oil it will 'be' necessary to deliver the oil through l`the burnerbypressuremeans sufficient to 3o secure delivery in enough quantity to produce the desired amount of combustion.

Other objects and advantages may hereinafterappear.

vation and partly in vertical mid section, of

the modification shown in Fig. 4. f

Fig. 5 is a section on line 5 5v of Fig. 3. Referring in. detail tov-thedra-wings, the

yrotary burner vhead 5 isprovided with a plusaid pipe 9 in an yend-wise-manner, it is possible to provide a working fit between said pipe and thetubular burner `head 5 without interfering burner head.

Said pivot pipe 9 is secured to the tubularV standard 10 by means of a fitting or coupling member 11 which is provided at its upper end with a central screw threaded bore intowhich the lower end of pipe 9 is screwed, and which has at its lower end an externally 'screw threaded extension 12 whereby it is screwed on to the upper end of standard 10:

Said fitting 11has an outwardly directed v flange 13 upon which is seated the concavoconvex heatradiating member 14. The upf per end of coupling 11 is provided with an externally lscrew 4threadedl portion 15 upon which is screwedthe lowerend of a dome-A shaped housing 16 which forms a combined guide and keeper for the burner head 5 during the rotation of said head. Saidh'ousing 16 is provided with a circular opening 1 in its: upper end which fits loosely around the ed Vwith an out-curved circumferentialvflange 18 the lower surface of kwhich contacts rotaty ably withl a convexity a of coupling member 11. Against'theooncavity formed yby the upper Side Ofsaid' flange 18 rest a series of ballwith the flow of the fuel to said y bearing members 19, said ball-bearing members being held in place by the upper contracted portion of the dome-shaped housing 16, which cooperates with the flange 18 to form a cage for said ball-bearing members.

A circular guard plate 20, in the form o'f a collar, is mounted upon the burner head 5 above the housing 16, said plate being provided with a downwardly extending skirt or flange a. Contained beneath said collar and flange is a leather or fabric guard 21 which is held in place by a clamping nut 22. Said guard 21 not only keeps dust and dirt out of the bearings, but is also of some value inl preventing the escape of gas. The lower portion of said guard moves lightly over the upper portion of the dome-shaped member 16 during rotation of burner head 5.

The outer portion of each burner arm v6 and 7 is provided with an apertured portion having an aperture and a deflected portion 26, said aperture 25 and said deflected portion 26 being so constructed and arranged' as to direct the issuing fuel tangentially to rotate said burner head. Each aperture or fuel vent 25 is formed as a narrow slit the length of which is directed at right angles to the plane of rotation of the burner head, the fuel vent of the arm 6 being directed oppositely to that of the arm 7.

The outer end portion of each of the burner tubes is flattened so as to form, as seen in side elevation, a head L, and this gives roomto provide a relatively long burner opening 25,

' this burner openingbeing formed by cutting away the outer end portion of one side of the flattened portion of the arm. The portion 26 of said arm opposite to this cut-away part is deiected as shown, in order to aid the issuing fuel to react effectively upon the atmosphere and produce a rapid rotation of the burner head together with its arms 6 and 7.

The standard 9 is shown screwed into a well known gas fixture Gr having a gas faucet 27.

Pivot tube 9 is provided at its upper end with an axial, diametrically contracted ertension 9?), of considerably less diameter than chamber 6, the upper end of which is pointed and bears against the lower concave end of adjustable bearing screw 9s which` is screwed into the upper end of the burner head 5. 9a is a lock nut to keep said screw from working loose.

Figs. 3, 4 and 5 illustrate a modification wherein the coupling member 11 and housing 16 of Fig'. 1 are combined to form a single supporting member for the rotary head 5x, said member 30 having a pivot pipe 9m screwed thereinto whereon said head 5m rotatc-s. This pivot pipe 9x is provided with an external circumferential groove having ports 36 which lead from said groove tothe interior of said pivot pipe. The rotary head 5a: is provided with tubular arms 6a: and 7a2 which register with groove 35 and therefore obtain a continuous fuel supply therefrom. The top screw 9;/ is screwed directly into the upper end of tube 9m, and by the aid of the washer 9fw holds the rotary head 5a: in place.

The heat radiating element 40 is secured by means of screws 41 to a flange 42 with which the member 30 is provided. 10m designates the standard or fuel supply pipe.

The fuel feeding arms 6x and 700 as best shown in section in Fig. 5, are each provided with a jacket 45 which, as seen in cross section is provided with a rear taper 46 and front taper 47 to diminish the resistance of the atmosphere to the rapid rotation `of the burner head', and to reduce agitation of the atmosphere within the circular path of the flame.

The form of the invention last described is intended more .particularly for use by jewelers, watchmakers and other artisans requiring asmall appliance, while the form first described is deemed preferable for use in ex,- panding large metallic rings and for heavy mechanical work. Medium sized heaters will be used for cooking and house heating.

In both forms of the invention the heat radiating element (14 or 40) houses the rotating burner arms sufficiently to form a combustion chamber.

Claims:

1. In a burner, a rotary burner head comprising a tubular body one end of which is closed and the other end of which is provided with an out-curved circumferential fiange, means operatively to support said head and 'to feed fuel thereto under pressure, said means comprising a standard juxtaposed to the 'flanged end of said head and a pivot pipe over which said head is rotatably fitted, a dome shaped housing mounted upon said standard and inclosing said ange in spaced relation thereto, and ball bearings contacting on one side with the interior of said housing and on the other side with the concave side of said outcurved flange, said housing and outward curved flange cooperating to form a cage for said ball bearings.

2. v In a burner, a rotary burner head compirsing a tubular body one end of which is closed and the other end of which is open, a stationary tubular support for said burner head having a working fit within the lumen of said tubular body, said support having fuel feed vents leading therefrom in an end- Wise manner'to supply fuel to said burner head and having a reduced extension directed towards the closed end thereof, and a ivot screw adjustably mounted in the close end of said burner head and having an anti-friction operative relation to said extension.

3. In a burner, a. rotary burner head having a plurality of tubular radially extending burner arms each of which is provided with a. burner aperture, the apertured-portions of said arms being constructed and arranged to direct the issuing gaseous fuel tangentially to Y rotate said burner head, means to operatively support said burner head and to supply fluid fuel thereto under pressure during its rotation, and a jacket mounted on each of said arms, said jacket having oppositely directed tapered portions todiminish atmospheric resistance and to reduce agitation of the atmosphere Within the path of the flame.

In testimony Whereoi'I We hereby aiiix our signatures.
